I seem to have a problem with subtitles in the latest version 1.71.0 for Windows, even though I have set always disable subtitles its showing subtitles. I even deleted the config and started from scratch but the problem persists.

I uninstalled 1.71.0 and installed the previous version 1.70.1 for Windows and using the same new config the subtitles are hidden again. Not sure if I just missed something obvious but I can't turn the subtitles off.

I can absolutely confirm this. Running the MKV file in WMP shows and hides the subtitles as expected depending on options. When streaming the file across to my PS3, the subtitles are always present even with the 'definitely hide subtitles' option in PMS is ticked.
